With the increasing demand for document transfer services such as the World Wide Web comes a need for better resource management to reduce the latency of documents in these systems. To address this need, we analyze the potential for document caching at the application level in document transfer services. We have collected traces of actual executions of… (More)

In this paper we overview the merits of a data dissemination mechanism that allows information to propagate from its producers to servers that are closer to its consumers. This dissemination reduces network traac and balances load amongst servers by exploiting geographic and temporal locality of reference properties exhibited in client access patterns. The… (More)

Telehealth provides an opportunity to reduce healthcare costs through remote patient monitoring, but is not appropriate for all individuals. Our goal was to identify the patients for whom telehealth has the greatest impact, as measured through cost savings and patient engagement. For prediction of cost savings, challenges included the high variability of… (More)

Telehealth provides an opportunity to reduce healthcare costs through remote patient monitoring, but is not appropriate for all individuals. Our goal was to identify the patients for whom telehealth has the greatest impact. Challenges included the high variability of medical costs and the effect of selection bias on the cost difference between intervention… (More)

A slightly shorter version of this TR will appear in Proc. Abstract With the increasing demand for document transfer services such as the World Wide Web comes a need for better resource management to reduce the latency of documents in these systems. To address this need, we analyze the potential for document caching at the application level in document… (More)
